Here, in alphabetical order, are 50 things to do or see in your RV before you die:

Capitol Reef National Park, Utah

Much of Capitol Reef is an inviting wilderness of sandstone formations such as Capitol Dome, Hickman Bridge, and Temple of the Sun and Moon in the backcountry of splendid Cathedral Valley. The central geologic feature, the Waterpocket Fold, is a bulging uplift of rainbow-hued sandstone “reefs” and canyons.

Rock art petroglyphs are abundant and tell the story of the early indigenous people, the Fremont Culture. Close by are the orchards of Fruita, an early pioneer settlement—and now headquarters for the park.

The Chihuahuan Desert, studded with spiky plants and lizards, offers little hint that what Will Rogers called the “Grand Canyon with a roof on it” waits underground. Yet, at this desert’s northern reaches, underneath the Guadalupe Mountains, lies one of the deepest, largest, and most ornate caverns ever found.

Water molded this underworld four to six million years ago. Some 250 million years ago, the region lay underneath the inland arm of an ancient sea. Near the shore grew a limestone reef. By the time the sea withdrew, the reef stood hundreds of feet high, later to be buried under thousands of feet of soil.

No place else on earth combines a deep, pure lake, so blue in color; sheer surrounding cliffs, almost two thousand feet high; two picturesque islands; and a violent volcanic past. It’s the deepest lake in the U. S. and its reputation as a spot of overwhelming, sublime natural beauty—the “Gem of the Cascades”—extends around the globe.

Approximately 7,700 years ago, 12,000 foot Mount Mazama erupted and collapsed on itself, forming a large, bowl-shape caldera. Remaining lava flows sealed the bottom and, after a long period of cooling, the caldera filled with rain and snow, creating the sapphire-blue lake.

Death Valley National Park, California

Death Valley National Park gives new meaning to the word extreme. Telescope Peak, the highest peak in the Park, rises 11,049 feet and lies only 15 miles from the lowest point in the United States in the Badwater Basin salt pan, 282 feet below sea level.

Hemmed in by nine mountain ranges, Death Valley is cut off from rainfall and cooling Pacific winds, making it one of the driest and hottest places in the world. The highest temperatures in the United States are regularly recorded here with a record high temperature of 134 degrees Fahrenheit in 1913.

Denali National Park, Alaska

Denali National Park is home to North America’s highest mountain, Mt. McKinley, towering over 20,300 feet tall. The 6 million acre National Park will also give you one of your best opportunities to see Alaska’s wildlife such as grizzly bear, moose, wolves, Dall sheep, and caribou.

The 90-mile road into Denali Park has restricted access and private vehicles are only allowed on the first fourteen miles. You will almost certainly want to travel further into the Park on a narrated bus tour or Park Service shuttle.

Everglades National Park, Florida

The park is at the southern tip of the Everglades, a hundred-mile-long subtropical wilderness of saw-grass prairie, junglelike hammock, and mangrove swamp that originally ran from Lake Okeechobee to Florida Bay.

The park’s unique mix of tropical and temperate plants and animals—including more than 700 plant and 300 bird species, as well as the endangered manatee, crocodile, and Florida panther—has prompted UNESCO to grant it international biosphere reserve status as well as World Heritage Site designation.
